6. Harry¹ Trevalga： You and your publication have unfairly discriminated² against my poems. I have submitted thirty poems in the last two years and you have not published any of them！ It is all because I won the Fenner Poetry Award two years ago and your poetry editor thought she deserved it.

　　Publisher： Ridiculous！ Our editorial policy and practice is perfectly³ fair, since our poetry editor judges all submissions⁴ for publication without ever seeing the names of the poets, and hence cannot possibly have known who wrote your poems.

　　The publisher makes which one of the following assumptions in replying to Trevalga's charges of unfair discrimination？

　　（A） The poetry editor does not bear a grudge⁵ against Harry Trevalga for his winning the Fenner Poetry Award.

　　（B） It is not unusual for poets to contribute many poems to the publisher's publication without ever having any accepted for publication.

　　（C） The poetry editor cannot recognize the poems submitted by Harry Trevalga as his unless Trevalga's name is attached to them.

　　（D） The poetry editor's decisions on which poems to publish are not based strictly⁶ on judgments⁷ of intrinsic merit.

　　（E） Harry Trevalga submitted his poems to the publisher's publication under his pen name.

　　7. In a study of the effect of radiation from nuclear weapons plants on people living in areas near them, researchers compared death rates in the areas near the plants with death rates in areas that had no such plants. Finding no difference in these rates, the researchers concluded that radiation from the nuclear weapons plants poses no health hazards to people living near them.

　　Which one of the following, if true, most seriously weakens the researchers' argument？

　　（A） Nuclear power plants were not included in the study.

　　（B） The areas studied had similar death rates before and after the nuclear weapons plants were built.

　　（C） Exposure to nuclear radiation can cause many serious diseases that do not necessarily result in death.

　　（D） Only a small number of areas have nuclear weapons plants.

　　（E） The researchers did not study the possible health hazards of radiation on people who were employed at the nuclear weapons plants if those employees did not live in the study areas.

　　8. It was once believed that cells grown in laboratory tissue cultures were essentially⁸ immortal⁹. That is, as long as all of their needs were met, they would continue dividing forever. However, it has been shown that normal cells have a finite reproductive limit. A human liver cell, for example, divides 60 times and then stops. If such a cell divides 30 times and then is put into a deep freeze for months or even years. It “remembers” where it stopped dividing. After thawing¹⁰, it divides another 30 times——but no more.

　　If the information above is accurate, a liver cell in which more than 60 divisions took place in a tissue culture CANNOT be which one of the following？

　　（A） an abnormal human liver cell

　　（B） a normal human liver cell that had been frozen after its first division and afterward¹¹ thawed¹²

　　（C） a normal cell that came from the liver of an individual of a nonhuman species and had never been frozen

　　（D） a normal liver cell that came from an individual of a nonhuman species and had been frozen after its first division and afterward thawed

　　（E） an abnormal cell from the liver of an individual of a nonhuman species

　　9. Complaints that milk bottlers take enormous markups on the bottled milk sold to consumers are most likely to arise when least warranted by the actual spread between the price that bottlers pay for raw milk and the price at which they sell bottled milk. The complaints occur when the bottled-milk price rises, yet these price increases most often merely reflect the rising price of the raw milk that bottlers buy from dairy farmers. When the raw-milk price is rising, the bottlers' markups are actually smallest proportionate to the retail¹³ price. When the raw-milk price is falling, however, the markups are greatest.

　　If all of the statements above are true, which one of the following must also be true on the basis of them？

　　（A） Consumers pay more for bottled milk when raw-milk prices are falling than when these prices are rising.

　　（B） Increases in dairy farmers' cost of producing milk are generally not passed on to consumers.

　　（C） Milk bottlers take substantially greater markups on bottled milk when its price is low for an extended period than when it is high for an extended period.

　　（D） Milk bottlers generally do not respond to a decrease in raw-milk prices by straightaway proportionately lowering the price of the bottled milk they sell.

　　（E） Consumers tend to complain more about the price they pay for bottled milk when dairy farmers are earning their smallest profits.

　　Questions 10-11

　　If the public library shared by the adjacent towns of Redville and Glenwood were relocated from the library's current, overcrowded building in central Redville to a larger, available building in central Glenwood, the library would then be within walking distance of a larger number of library users. That is because there are many more people living in central Glenwood than in central Redville, and people generally will walk to the library only if it is located close to their homes.

　　10 Which one of the following, if true, most strengthens the argument？

　　（A） The public library was located between Gienwood and Redville before being moved to its current location in central Redville.

　　（B） The area covered by central Glenwood is approximately the same size as that covered by central Redville.

　　（C） The building that is available in Glenwood is smaller than an alternative building that is available in Redville.

　　（D） Many of the people who use the public library do not live in either Glenwood or Redville.

　　（E） The distance that people currently walk to get to the library is farther than what is generally considered walking distance.

　　11. Which one of the following, if true, most seriously weakens the argument？

　　（A） Many more people who currently walk to the library live in central Redville than in central Glenwood.

　　（B） The number of people living in central Glenwood who would use the library if it were located there is smaller than the number of people living in central Redville who currently use the library.

　　（C） The number of people using the public library would continue to increase steadily¹⁴ if the library were moved to Glenwood.

　　（D） Most of the people who currently either drive to the library or take public transportation to reach it would continue to do so if the library were moved to central Glenwood.

　　（E） Most of the people who currently walk to the library would remain library users if the library were relocated to central Glenwood
